Cozumel is known for its miles and miles of pristine beaches and coastal areas. And all along the island's shoreline there are sand dunes piled up behind these beautiful beaches. As visitors walk along the water's edge and dig their toes into the soft sand, few realize that the health and beauty of the beaches are heavily dependent on the sand dunes just behind them. As more and more research is done on coastal eco-systems, scientists are now beginning to make us fully aware of the critically important role that sand dunes play in our global, coastal eco-systems.

Sand Dune Ecology

Sand dunes provide a wide range of habitats for a variety of unusual, interesting and adaptive plants that can cope with unstable habitats. Sand dunes form in relatively exposed locations. All over a dune, very specialized plants adapt to the accumulation of sand around them surviving the continual burial of their shoots by sending up very rapid vertical growth. With the help of these plant shoots, small mounds of vegetation and/or tide-washed debris can form and tend to enlarge as the wind-speed drops behind the mound, allowing blowing sand to fall out of the air stream and accumulate which constantly increases the size of a dune. The plants are physiologically adapted to withstand the problems of high salt contents in the air and soil. Sand dunes support a wide variety of colorful flowering plants, including a number of species of orchid.

On the inland side of dunes conditions are less severe, and typical grasslands develop containing a wide range of plant life. When enough humus has accumulated within the grassland sand, this more stabilized soil improves water retention and promotes further plant diversity development. Consequently, sand dune systems are excellent places for biodiversity, partly because they are not very productive for agriculture, and partly because these unstable and stable soil habitats are present in proximity to each other. Many dune areas are protected as nature reserves, and some are parts of larger conservation areas incorporating other coastal co-existing habitats like salt marshes, mud flats, grasslands, scrub and woodland.

All coastal dune ecosystems also support a population of animal species in addition to plant life. Since most animal life requires basic survival elements such as shelter, food and water, it stands to reason that species density in any one area would be dependent on their availability. Small birds, reptiles, crustaceans, and other coastal species commonly call the coastal dunes their home. As the dune system moves from the fore dunes toward the back dunes, with their increased vegetation, the ecosystem becomes more complex, supporting a larger amount of species. Sand dune systems are also very rich in invertebrates including butterflies, moths and burrowing bees and wasps.

The beach is a margin of sand in a dynamic ebb and flow controlled by tides, winds, currents and waves. The critical factor is the presence of a sufficiently large beach plain whose surface dries out between high tides. Off shore shallow sand banks release the initial energy from ocean swells as they break and send secondary waves with low residual energy gently up and down the beach. The dissipative beaches are wide, gently sloping, slow draining and quite firm underfoot because the fine sand particles fit close together. These beaches support a relatively high variety of burrowing organisms. Because of their shallow gradients, these beaches also act as traps for another group of organisms called diatoms. Diatoms survive between sand grains and provide the chief food for bi-valves and other filter feeders.

Recreation is a major land use on sand dune areas. Many dune systems are used extensively by tourists, mostly on foot but also for parking cars and in some cases for driving four-wheel-drive vehicles or motorcycles. Moderate pressure by pedestrians may cause little damage, however, excessive pedestrian use and vehicular use in particular, have caused unacceptable erosion on many dune sites.

Many dune systems also support one or more golf courses. Here much of the original vegetation may be retained in the rough, but the communities of the fairways, and particularly the greens and tees, are often severely modified by mowing, fertilizing and re-seeding. Sand dunes have also been affected in the past by housing developments, industrial development, and waste collection areas on or adjacent to them as well as sand extraction.

What can you do to help protect and conserve Cozumel’s sand dunes?

If you live part time or full time or vacation on the island:

Sign up & participate in ongoing beach cleanup efforts in Cozumel.

Keep your visits to the beaches “green” by not discarding trash. Leave the beach pristine. If you want to go beyond being an environmentally conscious visitor, there are a number of ways you can become proactive in the protection of our sand dunes. Pick up trash as you walk along the shore, and recycle or dispose of it properly. Encourage better behavior by other users; point out regulations and the reasons for them. Report any serious violation you see to the proper authorities.

If you must cross the dune, pick your way between the plants and avoid already-eroded trails and steep approaches. If there is more than one person, select spots where the dune is shallow and spread out; return to the beach by a different route.

Do not build fires on the beach. While dried driftwood makes great campfires, this and other natural debris washed up by the lake help trap sand, and are the only source of nutrients available for plant growth on the dunes. Also, beach campfires leave unsightly scars and pose a fire threat to surrounding vegetation in this dry habitat.

Do not ride all-terrain vehicles on the beach.

Do not disturb water birds, migrating shorebirds, and nesting shorebirds. They are extremely intolerant of visitors and are easily denied nesting habitat by the very presence of recreational beach/dune users.

If you are a golfer, encourage golf course management policies and practices that are sympathetic to the flora and fauna of sand dune systems.

Support legislation for sound management of the world’s coastal areas with your government.

Maintaining sandunes is essentional for Cozumel’s future.

We just came back from our Cozumel trip. We had a great time and really enjoyed the dolphin program. Thanks for giving our daughter such a great childhood memory!!!! By the way we came back to snow. Hope you are all enjoying the sunshine there!! The Francis family ~ Columbus, OH

My son and I decided to avoid the cruise ship excursions for snorkeling and try Pal Mar Estate Beach Club. I read a number of reviews and figured it was worth a shot. We have gone on 4 cruises now and always done the cruise line sponsored excursions and without a hesitation this is by far the best thing we have done. Pal Mar was nice, clean, very quiet and the staff was beyond awesome. One of the most relaxing times we have had. The Pico de Gallo was fresh and hand made and fantastic....my son wont touch tomatoes and such and he ate it all up...wonderful! The snorkeling was a lot of fun and we saw tons of fish, starfish, coral, etc. and even a Moray eel. Very cool and spooky too to be honest. We had a blast and would do it again in a heartbeat. With cab fare both ways, Pal Mar admission, 4 beers for me and two sodas for my son along with chips and Pico we spent only 65$. We snorkeled for almost 4 hours....exhausted but a blast! We must have seen at least 8 excursion trips come through the area we were at and they are there maybe 45 min to an hour and gone. It would have cost us 3 times what we paid to do the ship excursion and we got to relax and snorkel all day. Can't recommend it enough and we will definitely be back when our next cruise stops in Cozumel. Thank you so much for your hospitality!! M. Schomaker (Feb. 2015) ~ Elk River, MN

Sherri ~ WOW!!! We just returned from our cruise! What a wonderful time we had!! Your COZUMELINSIDER.com bookings for our Dolphin snorkel adventure and Sea Trek were the highlight of the cruise. They were easy and saved us about half the cost of booking through the cruise line. We simply hopped into a cab and spent the day at the Park (we could have spent a week there.) They were even able to work us into the Sea Trek early. All the people were friendly, helpful and overall just treated us great. While we were standing around waiting a short little man came up and ask if we wanted a snorkel tour. I instantly remembered what you had said and looked at his name tag. It was Mario! His tour was fantastic! If you see him ask him if he remembers Señor Ed and his family (he never caught that my name was Ted, but that’s okay!) I had a waterproof digital camera and he snapped lots of pictures of us. We had a wonderful time and much of it was thanks to you, your website and staff!

I know you probably get lots of pictures but I had to send you three. Look at the smiles on my boy’s faces. That says it all! Thank you so much for all your help and advice. We can’t wait to return. Your website is the first place we will stop! I wish we could have met in person. We will next time! T. Mahler Family ~ Howe ,TX

Sherri, We just returned after a great cruise on the Carnival Holiday. We took a taxi from the cruise pier to Palmar Estate Beach Club and spent about 1/2 a day at your beautiful place. We toured the butterfly sanctuary with your wonderful guide who was informative and very gracious. I also spent quite a bit of time talking to Juan and he was delightful. We relaxed, ate chips and salsa, drank pina coladas and soaked in the sun. What a delightful place you have and a wonderful staff that made our visit great. Thanks and if we get a chance to recommend your place to others we will surely do that.

PS: Your website warned us that the taxi drivers may not be too helpful when asked to go to Palmar Estates and you were correct. After asking 3 drivers who all sort of turned up their noses at us and acted like they had never heard of your place or the butterfly sanctuary we found one that would listen. I told him it was between Hotel Presidente & Fiesta Americana and he said OK. Anyway we got there in only about 6-8 minutes from the pier. Dale and Cathy Carlson ~ Louisville, KY
